Method and Apparatus with Access Authority Management

2. The method of claim 1, wherein the determining of whether the user corresponds to the multiple users or the single user comprises determining whether the user corresponds to the multiple users or the single user based on any one or any combination of any two or more of a number of the region of the at least one portion of the body, a color of the region of the at least one portion of the body, a position of disposition of the region of the at least one portion of the body compared to a position of the face region, an angle of disposition, and a size ratio of the region of the at least one portion of the body to the face region.

9. The method of claim 8, wherein the determining of whether the abnormal situation is detected comprises determining whether the other user is detected based on whether a plurality of face regions are detected in the second input image.

10. The method of claim 8, wherein the determining of whether the abnormal situation is detected comprises determining whether an object corresponding to the preset type of capturing device is detected in the second input image.

11. The method of claim 8, wherein the determining of whether the abnormal situation is detected comprises determining whether the capturing action, being of the user and corresponding to the preset type of capturing device, is detected in the second input image.

12. The method of claim 11, wherein the determining of whether the capturing action of the user is detected comprises determining whether the capturing action of the user is detected based on whether any one or any combination of any two or more of a pose of the user facing a screen provided through the system, a gesture of the user, a position of the capturing device corresponding to the screen, and consecutive motions of the user using the capturing device in the second input image corresponds to a motion predetermined as a capturing action.

13. The method of claim 1, further comprising guiding the user to transmit an image of a space outside a field of view corresponding to the input image by rotating a capturing device used to capture the input image and capturing the space, according to a security level corresponding to the system.

14. The method of claim 1, further comprising verifying whether the input image is captured by a capturing device with a polarizing film attached to narrow a field of view.

15. The method of claim 14, wherein the verifying comprises verifying, in response to the user wearing glasses, whether the input image is captured by a capturing device with a polarizing film attached to narrow a field of view, based on either one or both of a pattern and a color reflected on a lens of the glasses corresponding to the input image.

17. The method of claim 1, wherein the input image comprises an image obtained by capturing a working situation of the user who is telecommuting.

18. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, configure the processor to perform the method of claim 1.

21. The apparatus of claim 20, wherein, for the determining of whether the user corresponds to the multiple users or the single user, the processor is further configured to determine whether the user corresponds to the multiple users or the single user based on any one or any combination of any two or more of a number of the region of the at least one portion of the body, a color of the region of the at least one portion of the body, a position of disposition of the region of the at least one portion of the body compared to a position of the face region, an angle of disposition, and a size ratio of the region of the at least one portion of the body to the face region.

28. The apparatus of claim 27, wherein, for the determining of whether the abnormal situation is detected, the processor is further configured to determine whether the other user is detected based on whether a plurality of face regions are detected in the second input image.

29. The apparatus of claim 27, wherein, for the determining of whether the abnormal situation is detected, the processor is further configured to determine whether an object corresponding to the preset type of capturing device is detected in the second input image.

30. The apparatus of claim 27, wherein, for the determining of whether the abnormal situation is detected, the processor is further configured to determine whether the capturing action, being of the user and corresponding to the preset type of capturing device, is detected in the second input image.

31. The apparatus of claim 30, wherein, for the determining of whether the capturing action of the user is detected, the processor is further configured to determine whether the capturing action of the user is detected, based on whether any one or any combination of any two or more of a pose of the user facing a screen provided through the system, a gesture of the user, a position of the capturing device corresponding to the screen, and a motion of the user using the capturing device in the second input image corresponds to a motion suspected as a capturing action.

32. The apparatus of claim 20, wherein the processor is further configured to guide the user to transmit an image of a space outside a field of view corresponding to the input image by rotating a capturing device used to capture the input image and capturing the space, according to a security level corresponding to the system.

33. The apparatus of claim 20, wherein the processor is further configured to verify whether the input image is captured by a capturing device with a polarizing film attached to narrow a field of view.

34. The apparatus of claim 33, wherein the processor is further configured to verify, in response to the user wearing glasses, whether the input image is captured by a capturing device with a polarizing film attached to narrow a field of view, based on either one or both of a pattern and a color reflected on a lens of the glasses corresponding to the input image.

35. The apparatus of claim 20, wherein, for the receiving of the input image, the processor is further configured to receive either one or both of the input image according to a preset time interval and the input image according to a random time interval.
